This is what I get when I try to start the executable:

Mac-Pro:MacOS george$ /Applications/
dyld: Library not loaded: /usr/lib/libsqlite3.dylib
  Referenced from: /System/Library/Frameworks/Security.framework/Versions/A/Security
  Reason: Incompatible library version: Security requires version 9.0.0 or later, but libsqlite3.dylib provides version 1.0.0
/Applications/ line 131:  9870 Trace/BPT trap          "$prog" ${1+"$@"}

I also tried:

MacOS george$ open -a /Applications/Firefox

FSPathMakeRef(/Applications/Firefox) failed with error -43.

Is there a particular way to start the application from the command line?

The problem with your second attempt is that the path includes the .app extenstion.

Try using either

open -a /Applications/


open /Applications/

Correct. I verified. The "old hit tab key to autocomplete trick" fixes that one for me. – Grady Player Apr 29 '11 at 21:48
open -a Firefox works just as well (unless you have multiple instances of the same program installed). – Daniel Beck May 1 '11 at 0:35

These examples will open Firefox, open a specific website, or browse your user's home directory.

open -a firefox
open -a firefox -g
open -a firefox -g $HOME

If anyone is wondering about -g, it opens an application on the background, so that it will either be placed behind the frontmost application or have no visible windows. – ؘؘؘؘ Sep 19 '12 at 11:16

You want to run /Applications/
